After reading Major Nelson's post on used games and this article from Shack News, I can't help but think of ways to get past "biometric" DRM. I think this may be a whole new market for the blow up doll industry!
3 benefits of having a main account tied to a blow-up doll:
1) Portable: blow-up dolls can deflate. My friends and I can not evacuate our bodies and be easily dropped off with a used game.
2) Omnipresent: blow-up dolls of the same model can be at two locations at once so you can play the game in multiple places.
3) Cheap: much less expensive than trying to rent your friend for the day so you can play the new CoD.
That being said, a blow-up doll can be punctured so can you guys think of human-shaped analogues to trick the new DRM? I thought about getting a real-doll of myself to give to friends, but they don't seem to understand my future oriented frugality.
